The collection of medieval Welsh prose tales known as The Mabinogion tells of heroes on magical quests, knights-in-arms whose adventures take them to the far ends of the earth in pursuit of true love, and powerful women who sometimes betray and sometimes are betrayed.

The Mabinogion provides insight into Celtic mythology, Arthurian romance, and the performance techniques of the traditional storyteller. The Mabinogion is rightly regarded as a classic, translated by now into many languages, and adapted into childrens books, opera, plays, and more recently into animation.
